Re: 454 spark plug wires?
- Spark plug wires work, till they don't work. It typically is a engine miss that will tell you, you need new wires. The difference between a top of the line, and a cheaper (Autozone,O'reilly) is longevity. Probably any wire will work for years. For High performance, (hi RPM, etc) you need a top of the line wire. For an older Carbureted big block chevy, even in a motor-home, any wire should be OK.
